Sprinter® Boxwood

Sprinter® is the named Buxus microphylla cultivar ‘Bulthouse’, selected for fast growth and an upright, compact form. Proven Winners lists a mature height and spread of 2–4 feet, evergreen glossy green foliage, and performance in sun or shade. Its dense shape can fill a low hedge or formal edging quickly. ## Form and uses Use Sprinter as a low hedge, garden edging, foundation shrub, or container plant. Its upright habit suits structured plantings, while the published hardiness range is USDA zones 5–9. Mature dimensions vary with site, age, and trimming. ## Growing conditions Plant in moist, well-drained soil and water during establishment. Proven Winners describes average watering and exposure from sun to shade. The evergreen foliage offers year-round structure, while its small flowers are not a significant ornamental feature. ## Maintenance Pruning is seldom needed, though Proven Winners says the plant may be trimmed in summer. Water during prolonged dry weather, refresh mulch as needed, and inspect for common boxwood pests and diseases.
